敌敌畏是近两年来为部队所喜用的一杀虫剂。因其除有毒杀、触杀作用外,尚有良好的熏杀效果,且使用简便又无特殊气味,对人畜亦较安全,因之,在部队中经试用后很快即被推广。但因此药使用历史较短,经验还不多,在使用方法上尚存在着一些问题。据我们了解,主要有以下几个方面。(一)使用中如何保持药物的有效杀虫浓度、提高杀虫效果?药物的杀虫效果如何,主要取决于两个条件:一是昆虫对药物的耐受程度(即抗药性);另一个是药物的浓度和施药方法。前者在一定条件下能显著影响药物的杀虫效果。

The former under certain conditions can significantly affect the insecticidal effect of the drug.
